Answers

Answer 1

1. I believe the answer is D, y = fifth root of (x+4)/3
y = 3x⁵ - 4
Interchanging x and y
x = 3y⁵ - 4
solving for y in the equation; x=3y⁵-4
y = ((x+4)/3)^1/5

= ((x+4)/3)^1/5

2. inverse of the equation y = 3e^-4x+1
I think the answer is D;
Interchanging the variables x and y
x= 3e^-4y-1
Solving for y in x = 3e^-4y +1
y= -(In(x/3)-1)/4
= (1-In(x/3))/4

A toy rocket is launched from a platform 42 feet above the ground at a speed of 91 feet per second. The height of the rocket in feet is given by the polynomial −16t^2 + 91t + 42, where t is the time in seconds. How high will the rocket be after 3 seconds? HELP ASAP!!

A. 122 feetB. 218 feetC. 93 feetD. 2570 feet

Answers

Lets get started!

height = -16t² + 91t + 42
After 3 sec means, t = 3, so we substitute t with 3

H = -16(3)² + 91(3) + 42
= -144 + 273 + 42
= 171 feet

The height of the rocket after 3 seconds is 171 feet.

What is a function?

A function is defined as a relation between the set of inputs having exactly one output each.

The height = -16t² + 91t + 42

After 3 sec means, t = 3, so we substitute t with 3

In order to find the height of the rocket after t seconds we plugin t = 3 in the function.

height H = -16t² + 91t + 42

H = -16(3)² + 91(3) + 42

= -144 + 273 + 42

= 171 feet

Thus, the height of the rocket after 3 seconds = 171 feet.

The graph of f(x) has a domain of x <=–6.

Answers

the second option

hope this helps<3

Answer: B) The graph of f(x) is horizontally stretched.

Step-by-step explanation: We are given an absolute function [tex]f(x)=-\frac{2}{3} |x+4|-6[/tex].

The standard equation of an absolute function is [tex]f(x)= a|x-h|+k[/tex].

Where (h,k) is the vertex of the absolute function.

If we compare [tex]f(x)=-\frac{2}{3} |x+4|-6[/tex] and [tex]f(x)= a|x-h|+k[/tex], we can see a=[tex]-\frac{2}{3}[/tex], h= -4 and h= -6.

Therefore, vertex of the given function is (-4,-6).Because we have value of a is a negative number so it would open down.An absolute function always have domain " All real numbers".

Therefore, first, third and fourth options are incorrect.

So, the second option would only be applicable.

What is the solution of x+4/2x-1<0 ?

Answers

To solve the inequality x + 4/2x - 1 < 0, first find the critical value x = 1/2. Then, test the intervals to determine the solution set x < 1/2.

To find the solution of the inequality x + 4/2x - 1 < 0, we can follow these steps:

First, find the critical values by setting the denominator, 2x - 1, equal to zero and solve for x. The critical value is x = 1/2.

Next, test the intervals created by the critical value in the original inequality x + 4/2x - 1 < 0. This helps determine the solution set which is x < 1/2.

The answer to this is 65.

Remember that the angles opposite of each other equal to 180. So a+c=180 and b+d=180.

First, we solve for x. Since we know that b and d equal to 180, we subtract 148 from 180.
180-148=32. x=32.

Then we plug that in the expression for angle a.
2x+1 becomes 2(32)+1
2*32=64
64+1=65.

Answers

first answer is 81.39 but can't picture the second one without a figure

Answer:

1) the slant height of the pyramid is 50 meters.

2) there are (approximately) a total of 80 ft of laser beams.

Step-by-step explanation:

1) The height of the pyramid (30 m) and half of the length of its base (40 m) form a rectangular triangle, where the slant height is its hypotenuse (H). From Pythagorean theorem:

H^2 = 30^2 + 40^2

H = √2500

H = 50 m

2) In the figure attached the rectangular prism is shown (point E was added).

The length of the laser beams is the addition of the segments AD to segment CB (which are equal).

We can make a rectangular triangle between points ECD. From Pythagorean theorem:

ED^2 = EC^2 + CD^2

ED = √(12^2 + 35^2)

ED = 37 ft

We can make a rectangular triangle between points AED. From Pythagorean theorem:

AD^2 = EA^2 + ED^2

AD = √(15^2 + 37^2)

AD ≈ 40

Then, there are (approximately) a total of 80 ft of laser beams.

Jacey obtains a 30-year 6/2 ARM at 4% with a 2/6 cap structure in the amount of $224,500. What is the monthly payment during the initial period?

Answers

In this case we have an ARM fixed for 6 years and adjust after the initial first 6 years every 2 years after. The basic idea behind a ARM is that the interest changes periodically, but since our ARM is fixed for 6 years, our going to calculate the monthly payment during the initial period using the formula: [tex]m= \frac{P( \frac{r}{12}) }{1-(1+ \frac{r}{12})^{-12t} } [/tex]
where
[tex]m[/tex] is the monthly payment
[tex]P[/tex] is the amount
[tex]r[/tex] is the interest rate in decimal form
[tex]t[/tex] is the number years

First we need to convert our interest rate of 4% to decimal form by dividing it by 100%:
[tex] \frac{4}{100} =0.04[/tex]
We also know from our question that [tex]P=224500[/tex] and [tex]t=30[/tex], so lets replace those values into our formula to find the monthly payment:
[tex]m= \frac{224500( \frac{0.04}{12}) }{1-(1+ \frac{0.04}{12})^{-(12)(30)} } [/tex]
[tex]m=1071.80[/tex]

We can conclude that the monthly payment during the initial period is $1071.58

y + 2 = -2 ( x - 3 )

y + 2 = -2 x - 2(- 3)

y + 2 = -2 x + 6

y = -2 x + 6 - 2

y = -2 x + 4

the distance light travels in one second (one light-second) is about 1.86 x 10^5 miles. Saturn is about 475 light-seconds from the sun. About how many miles from the sun is saturn?

Answers

the distance light travels in one second (one light second ) - 1.86 x 10^5 miles
Saturn is 475 light seconds away from the sun. Using this information we are asked to find the distance saturn is away from the sun.
1 light second - 1.86 x 10^5 miles
Therefore 475 light seconds -1.86 x 10^5 miles/light second * 475 light seconds
= 8.83 x 10^7 miles
Saturn is 8.83 x 10^7 miles away from the sun

Answer:

Step-by-step explanation:

Given that the distance light travels in one light second about

[tex]1.86(10^5) miles[/tex]

Distance of Saturn from Sun = Time taken for travel x speed

Here speed = [tex]1.86 x 10^5[/tex]

Time taken = 475 light seconds

Hence distance = [tex]1.86 x 10^5x475\\=883.5x10^5\\=8.835x10^7[/tex] miles

Carolyn has cut a piece of ribbon 29 centimeters long from a roll. which instrument would she use to measure the length of the piece of ribbon?

Answers

Final answer:

Carolyn would use a ruler to measure the length of the piece of ribbon.

Explanation:

To measure the length of a piece of ribbon, Carolyn would use a ruler as the instrument. A ruler is a tool used for measuring small items and distances. It is commonly used for measuring in inches, which is the appropriate unit for short lengths like a piece of ribbon. Carolyn can align one end of the ribbon with the zero mark on the ruler and then extend the ribbon along the ruler to measure its length accurately.

The ruler's precision in measuring small distances, typically in inches, allows Carolyn to obtain a detailed and accurate measurement for the ribbon's length. Aligning the ribbon's end with the ruler's zero mark ensures a standardized starting point for consistency in measurements. This straightforward method showcases the practicality and ease with which rulers facilitate precise length measurements, making them essential tools for tasks requiring accuracy in determining dimensions.

b. 3s+3+3(7s-2)= 52
c. s+(7s-2)=52
d. (s-3)+(7s-2)-3=52

Answers

First,
the age of the son: s
the age of the father is 2 less than 7 times the age of his son: 7s - 2
In 3 years, the sum of their ages will be 52,
In 3 years, the age of the sun will increase 3, so s+3. Also, the age of his father also increase 3, (7s - 2) + 3

(s+3) + [(7s-2) + 3] = 52 is the equation.

Answers

These are five questions and five answers.

Part 1.] Identify the following series as arithmetic, geometric, both, or neither. Includes picture

Answer: arithmetic

Justification:

The arithmetic series are those in which the distance (difference) between any consecutive terms is constant, so you can find the term An adding the difference to the previous term, A(n-1).

In this case the series is:

∞
∑ (3 + na) =>
n=1

Term1: 3 + a
Term2: 3 + 2a
Term3: 3 + 3a
Term3: 3 + 4a

As you see, the difference between two consecutive terms is a, which shows that it is an arithmetic series.

Part 2.] Evaluate C(3, 3)
A.] 1
B.] 6
C.] 24

Answer: option A) 1.

Explanation:

The formula for combinations is Cm,n = m! / [n! (m - n)! ]

So, for C3,3, C3,3 = 3! / [3! 0!] = 3! / 3! = 1.

From this you might learn that Cm,m for any m is always 1.

Part 3.] Evaluate C(6,3)
A.] 20
B.] 120
C.] 720

Answer: option A) 20

Explanation:

Use the same formula, Cm,n = m! / [n! (m - n)! ]

C6,3 = 6! / [3! 3! ] = 6*5*4 / (3*2*1) = 5*4 = 20

Part 4.] How many subsets of four elements each exist in a set of seven elements?
A.] 4!
B.] C(7, 4)
C.] P(7, 4)

Answer: option B) C(7,4)

Explanation

You have to select collections of 4 elements from a set of 7 elements, and must realize that the order is irrelevant, i.e. it is the same the set ABCD as the set ACBD or DCAB or any combination of those four elements. So, the answer is a combination and not a permutation.

The number of subsets of 4 elements that you can form with 7 elements is: C(7,4), which is the option B.

Part 5.] What is the probability of having 3 children that are all boys?
A.] 1/2
B.] 1/8
C.] 3/8

Answer: option B: 1/8

Explanation:

The number of possible outcomes is 2 * 2 * 2 = 8

Only one of those outcomes is for all boys = 1

Therefore the probability is 1/8

You can see that representing the possible outcomes using B for boys and G for girls:

1) BBB (three boys)
2) BBG

3) BGB
4) BGG

5) GBB
6) GBG

7) GGB
8) GGG

Those are the 8 possible outcomes and as seen only one is for 3 boys.

Solve the following equation. Then place the correct number in the box provided. 9(x - 6) = 8(x + 6)

x=

Answers

Hello!

9(x - 6) = 8(x + 6)

The first step to take here is to apply the Distributive Property, which is
a(b + c) = ab + ac.

9(x - 6) = 8(x + 6)
9x - 54 = 8x + 48

After this, you want to begin to eliminate terms to ultimately isolate x; you can subtract 8x from both sides first:

9x - 54 = 8x + 48
x - 54 = 48

Finally, add 54 to both sides to get x by itself:

x - 54 = 48
x = 102

Answer:
x = 102

The answer is 102.
9(x -6) = 8(x+6)
9x - 54= 8x +48
x- 54= 48
x= 102
